When the landing gear handle was selected to the down position in preparation for landing, the landing gear would not extend electrically. The flightcrew executed an abnormal checklist, which included utilizing a mechanical hydraulic pump; however, the landing gear remained retracted. The flightcrew elected to land the airplane with the gear retracted. Examination of the landing gear system revealed that maintenance personnel had improperly installed the landing gear service valve 6 days prior, by reversing two hydraulic lines. Reasons for the electrical malfunction of the landing gear service valve could not be determined. The airplane's maintenance manual did not refer to the cycling of the landing gear, mechanically or electrically, after replacement of the landing gear service valve.
Probable Cause: The reversal of landing gear hydraulic lines by company maintenance personnel. Factors related to the incident were the manufacturers omission of maintenance procedures, and the failure of an electrical switch for undetermined reasons.
